A new method to test the valence quark distribution of nucleon obtained fromthe maximum entropy method using Gottfried sum rule by performing DGLAPequations with the GLR-MQ-ZRS corrections and original LO~/~NLO DGLAP equationsare outlined. The test relies on a knowledge of the unpolarized electron-protonstructure function $F_2^{ep}$ and electron-neutron structure function$F_2^{en}$ and the assumption that Bjorken scaling is satisfied. In this work,the original Gottfried summation value obtained by the integrals of thestructure function at different Q$^{2}$ is in accordance with the theoreticalvalue 1/3 under the premise of light-quark flavour symmetry of nucleon sea,whether it is the result from the dynamics evolution equations or the resultfrom global QCD fits of PDFs. Finally, we present the summation value of the LO/ NLO DGLAP global fits of PDFs under the premise of light-quark flavourasymmetry of nucleon sea. According to analysis the original Gottfriedsummation value with two evolution equations at different $Q^{2}$, we can knowthat the valence quark distributions of nucleon obtained by the maximum entropymethod are effective and reliable.
